well-lit by bright glow-plates imbedded in the walls of the buildings, but above the street level, the buildings themselves loomed darkly. Occasionally, an Exec's aircar would drift rapidly overhead with a soft rush of air, and, in the distance, he could see the shimmering towers of the Executive section rising high above the eight- or ten-storyed buildings that made up the majority of Bellinberg. The streets were fairly crowded with strollers—most of them Class Four or Five citizens who stepped deferentially aside as soon as they saw his uniform, and kept their eyes averted from him. Now and then, the power car of a Class Three rolled swiftly by, and The Guesser felt a slight twinge of envy. Technically, his own rank was the equivalent of Class Three, but he had never owned a groundcar. What need had a spaceman of a groundcar? Still, it would be nice to drive one just once, he thought; it would be a new experience, certainly. Right now, though, he was looking for a Class Three bar; just a place to have a small, quiet drink and a bite to eat. He had a perfect right to go into a lower class bar, of course, but he had never felt quite comfortable associating with his inferiors in such a manner, and certainly they would feel nervous in his presence because of the sidearm at his hip. No one below Class Three was allowed to carry a beamgun, and only Ones and Twos were allowed to wear the screening fields that protected them from the nerve-searing effects of the weapon. And they, being Execs, were in no danger from each other. Finally, after much walking, he decided that he was in the wrong part of town. There were no Class Three bars anywhere along these streets. Perhaps, he thought, he should have gone to the Spacemen's Club at the spaceport itself. On the other hand, he hadn't particularly wanted to see any of the other minor officers of his own class after the near-fiasco which had damaged the Naipor. Being a Guesser set him apart, even from other Threes. He thought for a moment of asking a policeman, but he dismissed it. Cops, as always, were a breed apart. Besides, they weren't on the streets to give directions, but to preserve order. At last, he went into a nearby Class Four bar and snapped his fingers for the bartender, ignoring the sudden silence that had followed his entrance. The barman set down a glass quickly and hurried over, bobbing his head obsequiously. "Yes, sir; yes, sir. What can I do for you, sir? It's an honor to have you here, sir. How may I serve
